YouTube offers built-in automatic captions that are displayed by default to viewers.

But these are not perfectly accurate and easy to customize.

In this guide, we’ll explore various methods to add captions and subtitles to your YouTube Shorts effectively.

Does YouTube Shorts Have Auto Captions?

Yes, YouTube Shorts has an auto-caption feature that automatically transcribes spoken words into text just like for normal YouTube videos.

YouTube’s auto-captioning system relies on AI-powered speech recognition to generate subtitles. These captions appear in sync with your spoken words and can be edited later for accuracy. When a creator uploads a video, YouTube processes the audio and generates captions automatically. This feature works for most languages, but availability may vary depending on region and video language.

If your channel has captions enabled by default, YouTube will automatically generate subtitles for your Shorts. However, creators can always review and edit these captions in YouTube Studio to correct any errors. Since AI-generated captions may occasionally misinterpret words, it’s important to double-check them before publishing your video.

How to Use YouTube Auto Captions on Shorts

YouTube’s built-in captioning tool automatically transcribes your video’s audio. Follow these steps to enable and edit auto captions for your Shorts.

Step 1: Upload or Record Your YouTube Short

Open YouTube Studio and navigate to the Create section. Record a new Short or upload an existing video. Ensure your audio is clear, as YouTube’s speech recognition technology works best with minimal background noise and clear pronunciation.

Step 2: Enable Auto Captions

Once your video is uploaded, YouTube will automatically process the audio and generate captions. To check if captions are enabled:

  • Go to YouTube Studio.
  • Select Subtitles from the left-hand menu.
  • Click on the video where you want to add captions.
  • If auto captions are available, they will appear under the Published or Draft section.

If captions are not automatically generated, ensure that your channel settings allow captions by going to Settings > Upload defaults > Advanced Settings and enabling Automatic captions.

Step 3: Review and Edit Captions

YouTube’s AI-generated captions are generally accurate, but errors may occur, especially with fast speech, technical terms, or background noise. To edit captions:

  • Click on the Auto-generated captions in the Subtitles section of YouTube Studio.
  • Use the text editor to modify any incorrect words or phrases.
  • Adjust the timing if necessary to ensure synchronization with the spoken audio.
  • Click Publish to save your changes.

Step 4: Customize Captions for Better Readability

While YouTube does not offer extensive customization for auto captions, you can improve their readability by:

  • Ensuring proper punctuation and sentence breaks.
  • Removing filler words or incorrect transcriptions.
  • Keeping captions concise and aligned with the video’s pacing.

Step 5: Publish Your Video with Captions

Once you’re satisfied with your captions, click Save & Publish. Your video will now display accurate subtitles to all viewers. Captions will automatically be available for those watching with sound off or needing transcription.

How to Add Captions Manually on YouTube Shorts

If you prefer full control over your captions, YouTube allows you to add them manually. This method ensures that your subtitles are accurate and well-timed, providing a better experience for your audience. Follow these steps to manually add captions to your Shorts.

Step 1: Upload or Record Your Video

Begin by uploading a new Short or recording one directly in the YouTube app. Ensure the audio is clear and well-paced for easier captioning.

Step 2: Open YouTube Studio

  • Go to YouTube Studio.
  • Click on Subtitles in the left-hand menu.
  • Select the video where you want to add captions.

Step 3: Add Captions Manually

  • Click Add Language and choose the language of your captions.
  • Select Add manually to enter your captions line by line.
  • Type the captions in sync with the video’s audio.
  • Use YouTube’s timeline editor to adjust the timing and ensure accuracy.

Step 4: Upload a Subtitle File

If you have a pre-made caption file (e.g., .srt or .vtt), you can upload it instead of typing manually:

  • Click Upload file under the Subtitles section.
  • Select the correct format and upload your file.
  • Adjust any necessary timing or text formatting.

Step 5: Review and Save

  • Play the video to ensure the captions are correctly synced.
  • Edit any mistakes or misaligned text.
  • Click Save & Publish to make your captions live.

How to Turn Off Subtitles on YouTube Shorts

If you prefer to watch YouTube Shorts without captions, you can disable them easily. Here’s how to turn off subtitles:

For Viewers:

  • While watching a Short, tap the CC (Closed Caption) button.
  • Select Turn off captions to disable subtitles for that video.

For Creators:

  • Open YouTube Studio.
  • Click on Subtitles in the left-hand menu.
  • Select the video where you want to disable captions.
  • Click on More Options and select Delete Captions.

How to Generate Quality YouTube Shorts Captions & Subtitles

While YouTube’s built-in auto-captioning system is useful, it’s not always perfect. For more control over accuracy, timing, and styling, you can use external tools like Checksub to create professional captions :

Step 1: Upload Your Video

Start by logging into Checksub. Upload your YouTube Short by selecting the video file from your device. Checksub supports various video formats, making it easy to work with your content.

After uploading, choose the original language of your video. If you want to reach a global audience, you can also select additional languages for translation. This feature ensures your content is accessible to viewers worldwide.

Step 2: Generate & Edit AI-Powered Subtitles

Once the video is uploaded, Checksub will automatically transcribe the audio using advanced AI-driven speech recognition. The process usually takes just a few minutes, depending on the length and complexity of your video.

After transcription, you’ll be able to review and refine the generated captions. Checksub’s online editor allows you to:

  • Correct any misinterpretations or errors.
  • Split or merge subtitle lines for better readability.
  • Adjust timing to ensure the subtitles are perfectly synchronized with the spoken words.

Checksub also offers customization options to help you match the captions to your video style. You can:

  • Change the font, size, and color of the text.
  • Adjust the placement of the captions on the screen.
  • Add background effects to improve visibility.

Step 3: Export and Upload Subtitles to YouTube

Once you’re satisfied with your captions, you can export them in multiple formats, such as SRT, VTT, or embedded text. If you want to manually upload them to YouTube, follow these steps:

  • Open YouTube Studio.
  • Navigate to Subtitles.
  • Click on the Upload file option and select the correct subtitle file.
  • Adjust the timing if necessary and Save & Publish.

Alternatively, you can embed the subtitles directly into the video, ensuring that captions are always visible, even when auto-captions are turned off.
